Abstract (en)

[origin: EP2605617A1] The present invention relates to a method of heating a load using microwaves and a microwave heating apparatus. The microwave heating apparatus (100) comprises a cavity (130) dividable into at least two compartments, a first microwave generator (111) and a first feeding port (141) for feeding a first mode field in a first compartment (131) of the cavity, a second microwave generator (112) and a second feeding port (142) for feeding a second mode field in a second compartment (132) of the cavity. The first mode field and the second mode field provide complementary heating patterns in the cavity when the cavity is undivided. The present invention is advantageous in that it provides the flexibility of heating a load in a large cavity or heating a plurality of loads in smaller compartments of the cavity while still providing even heating in the cavity and in the compartments.
